Hi yoyoyhyh1,Welcome to Microsoft Answers Forum.A.Do you face this problem on wired or wireless?B.Do you get any error message?C.Check if that device is getting detected in device manager?

I would suggest you to update the network card drivers from the manufacturer’s website and see if that helps.1.Open Device Manager by clicking the Start button, clicking Control Panel, clicking System and Maintenance, and then clicking Device Manager.‌ If you are prompted for an administrator password or confirmation, type the password or provide confirmation.2.In Device Manager, locate the device you want to update, and then double-click the device name.3.Click the Driver tab, and then click Update Driver and follow the instructions.Additional Information: http://windows.microsoft.com/en-us/windows-vista/Update-a-driver-for-hardware-that-isnt-working-properlyif that does not help, I would suggest you to disable all firewalls on the computer and then connect the external devices like Skype and see if that helps.Troubleshoot network connection problemshttp://windows.microsoft.com/en-us/windows-vista/Troubleshoot-network-connection-problemsWireless networking questions http://windows.microsoft.com/en-US/windows7/Wireless-networking-frequently-asked-questionsNetwork connectivity fails when you try to use Operating system behind a firewall devicehttp://support.microsoft.com/kb/934430Hope this helps.Let us know the results.Thanks & Regards, Vijay – Microsoft Support Visit our Microsoft Answers Feedback Forum and let us know what you think
